To study the toxicity and efficacy of simultaneous cisplatin chemotherapy and radiation therapy, 13 patients with metastatic solid tumors were treated with cisplatin on a weekly, outpatient basis during palliative radiation therapy. The dose of cisplatin ranged from 20 to 50 mg/m2 weekly, with most patients receiving 40 mg/m2. Radiation therapy was administered in a variety of dose-fraction schedules. Toxic effects were moderate and consisted of emesis (12 patients), transient elevation off BUN (three patients), myelosuppression (three patients), and radiation reactions (two patients). Twelve of 13 irradiated lesions (91%) responded with at least a 50% reduction in biperpendicular diameter. Four of the six patients with metastatic melanoma had complete regression of treated lesions; another melanoma patient had a partial response. Responses were also seen in patients with mesothelioma, bladder cancer, squamous cell carcinoma of the head and neck, and oat cell lung cancer. Only one responding patient has had disease progression in the treated field after 2+ to 7+ months of followup; two other patients have died of disseminated disease. Weekly cisplatin administration during radiotherapy deserves further evaluation, especially in the primary management of unresectable tumors that are responsive to cisplatin alone.

To define the activity of an individually escalated dacarbazine (DTIC) dose combined with interferon-alpha-2a (IFN), granulocyte-colony stimulating-factor (G-CSF) and ondansetron, 20 patients (pts) with metastatic melanoma were treated with DTIC, ondansetron 8 mg iv, G-CSF 300 micrograms sc and IFN 9 MU sc. Treatment was performed every 21 days to a maximum of 6 courses. DTIC dose was escalated with 250 mg/m2 in case of acceptable toxicity to 1250, 1500 and 1750 mg/m2 in (projected/realized), 14/19, 8/11 and 0/5 pts, respectively. Dose escalation prohibiting toxicities were thrombocytopenia (10 pts), leukopenia (9 pts), and nausea/vomiting (2 pts). Four partial remissions were observed, for a response rate of 20% (95% confidence interval, 6 to 44%). Duration of responses was 1, 2, 3 and 3 months. Median overall survival was 8 months.

Both chemotherapy and interleukin-2 and/or interferon-alpha produce objective responses in a proportion of advanced malignant melanoma patients. While duration of response to chemotherapy is short, i.e. usually below 4 months, immunotherapy has resulted in a small number of long-lasting remissions in patients with metastatic melanoma. In two consecutive phase II trials in a total of 67 patients, we assessed the potential synergism between both modalities, i.e. chemo- and immunotherapy. Treatment consisted of intravenous (i.v.) carboplatin (CBDCA, 400 mg/m2) and dacarbazine (DTIC, 750 mg/m2) given twice (i.v. bolus over 30 min) at 3-week intervals, or 4 cycles of DTIC (220 mg/m2 i.v. 3 days), cisplatin (DDP, 35 mg/m2 i.v. 3 days), carmustine (BCNU, 150 mg/m2 i.v. cycles 1 and 3) and tamoxifen (TAM, 20 mg oral/daily) at 3-week intervals. Chemotherapy was followed by immunotherapy with combined subcutaneous (s.c.) interleukin-2 (rIL-2) and SC interferon-alpha 2 (rIFN-alpha). Among 40 patients who received a full cycle of chemotherapy with CBDCA/DTIC and sequential immunotherapy, there were 3 (7.5%) complete remissions (CRs) with a median duration of 19 months (range 13-26+). Partial remissions (PRs) were noted in 11 (27.5%) patients with a median response duration of 8 (range 5-14) months. Among 27 patients who received DTIC/DDP/BCNU/TAM and rIL-2/rIFN-alpha, there were 3 (11%) complete remissions and 12 (44.5%) partial remissions. Duration of complete and partial remissions ranged from 9+ to 13+ (median, 11+), and 5 to 15+ (median, 7+) months, respectively. Chemotherapy produced mostly moderate toxicity. Thrombocytopenia was common with the nadir after a median time of 18 days following start of CBDCA/DTIC and DTIC/DDP/BCNU, respectively. 10 patients required transfusion of thrombocytes. Nausea and vomiting due to chemotherapy were well tolerated using concomitant ondansetrone (8 mg i.v.). Immunotherapy was self-administered at home with mild to moderate side effects; malaise, fever, chills, nausea/vomiting, diarrhoea, anorexia and arthralgias were most frequent, but were spontaneously reversible after ending rIL-2/IFN-alpha. A mean 87 and 88% of the projected doses of rIL-2 and rIFN-alpha were administered on either protocol. There were no life-threatening complications and no treatment-related deaths. The sequential combination of chemotherapy and rIL-2 plus rIFN-alpha had at least additive therapeutic activity against metastatic malignant melanoma. The schedules produced long-lasting remissions and were tolerated well overall. These trials substantiate a potential role for low to intermediate dose immunotherapy in maintaining and consolidating therapeutic effects of chemotherapy in metastatic melanoma.

A third-generation platinum analogue, zeniplatin, was administered at a dose of 145 mg/m2 intravenously over 60-90 minutes every 21 days as the initial chemotherapy to 21 patients with metastatic melanoma. Prehydration and mannitol diuresis was introduced after the first 7 patients. There were 17 males and 4 females. The median age was 52 (range: 29-81). ECOG performance status was 0 in 10 patients, 1 in 8 patients and 2 in 3 patients. Major disease sites were lymph nodes, skin, lung, liver, and bone. Patients received a median of 2 cycles (range: 1-7). Two patients achieved partial responses. One with nodal disease progressed after 166 days and the other with buccal mucosal disease after 142 days. A third patient showed partial regression of nodal disease but developed cerebral metastases. Gastrointestinal toxicity included WHO grade 3 vomiting in 8 patients and nausea in 2. Antiemetics were used, but ondansetron was not available. WHO grade 3 hematologic toxicities included neutropenia in 8 patients and anemia and thrombocytopenia in 1 patient. Thrombocytosis was seen in 35% of courses. Dosage reduction was required in 15% of courses and escalation in 5% of courses. Three patients developed phlebitis related to the infusion. One patient developed a reversible rise in serum creatinine, but, unlike other studies, no severe nephrotoxicity was reported. Zeniplatin demonstrated only modest activity in melanoma with significant gastrointestinal and hematologic toxicity.

Two cases of metastatic malignant melanoma of the lower limb who were treated successfully with hyperthermic isolated limb perfusion are reported. One patient was infused with cisdiammine (1.1-cyclobutanedicarboxylate) platinum (II) (carboplatin, Paraplatin, Bristol-Myers Squibb Company, New Jersey, USA), and the other was infused with human natural beta-interferon (Feron, Toray, Tokyo, Japan), via the external iliac artery. The first case showed a remarkable suppression of the growth of multiple metastatic melanoma nodules associated with numerous melanophage infiltrations, as shown histopathologically after the operation. The patient's serum level of 5-S-cysteinyl dopa decreased for the two months following the treatment. In the second case, new formation of metastatic melanoma nodules was completely suppressed for up to 12 months following the operation. Analysis of immunological parameters showed that the number of peripheral CD8+ lymphocytes gradually and constantly increased after the operation, while that of CD4+ lymphocytes transiently increased and then returned to the pre-operative level. Natural killer activity transiently decreased to a slight degree 4 days after the operation and then returned to the pre-operative level 21 days after the operation. Side effects, such as nausea, vomiting and leg discomfort, were seen in the patient (Case 1) treated with carboplatin, but were completely reversible. These results suggest that hyperthermic isolated limb perfusion with concomitant infusion of carboplatin or beta-interferon is effective in suppressing the growth of metastatic malignant melanomas of the lower limb.

The toxicity and clinical response to treatment with the combination of interferon-gamma (IFN-gamma) and interleukin-2 (IL-2) in patients with metastatic melanoma was evaluated. From May 1993 through February 1994, 20 patients were treated with 24 courses of IFN-gamma with or without IL-2. A 7-day course of subcutaneous IFN-gamma alone was administered to cohorts of two or three patients each at doses of 0.1, 0.2, or 0.3 mg/m2. Thirteen patients received escalating doses of IFN-gamma between 0.2 and 0.5 mg/m2 followed by the intravenous (i.v.) administration of IL-2 (720,000 IU/kg) given three times a day. A treatment course consisted of two cycles (maximum of 15 doses of IL-2 per cycle) separated by a 10-day interval. Five additional patients were treated with five courses of IFN-gamma, IL-2, and tumor-infiltrating lymphocytes (TILs). All patients treated had the diagnosis of metastatic melanoma. The maximal tolerated dose of subcutaneous IFN-gamma was established at 0.3 mg/m2 with dose-limiting hepatotoxicity. Immunohistochemistry analyses showed detectable upregulation of MHC class I alleles in one (8%) of 12 patients. Two of 20 patients who received the combination of IFN-gamma and IL-2 had responses, one partial and one complete response. The duration of response was 7 months for the partial response and 12 months for the complete response. IFN-gamma was tolerated with minimal side effects of nausea, vomiting, malaise, and decreased hematopoiesis. No increased toxicities were found with the combination treatment, as compared with IL-2 alone. One death occurred on the third day of treatment with IFN-gamma alone from hemorrhage into brain metastases. There were no responders in the five patients who received the combination treatment of TIL, IL-2, and IFN-gamma. From these findings, we conclude that further studies looking at this combination treatment are not warranted.

Bryostatin 1 is a protein kinase C partial agonist which has both antineoplastic and immune-stimulatory properties, including the induction of cytokine release and expansion of tumour-specific lymphocyte populations. In phase I studies, tumour responses have been observed in patients with malignant melanoma, lymphoma and ovarian carcinoma. The dose-limiting toxicity is myalgia. Sixteen patients (age 35-76 years, median 57 years) with malignant melanoma were treated. All had received prior chemotherapy. In each cycle of treatment, patients received bryostatin 25 degrees g m(-2) weekly for three courses followed by a rest week. The drug was given in PET diluent (10 microg bryostatin ml(-1) of 60% polyethylene glycol, 30% ethanol, 10% Tween 80) and infused in normal saline over 1 h. The principal toxicities were myalgia (grade 2, eight patients and grade 3, six patients) and grade 2 phlebitis (four patients), fatigue (three patients) and vomiting (one patient). Of 15 patients evaluable for tumour response, 14 developed progressive disease. One patient developed stable disease for 9 months after bryostatin treatment. In conclusion, single-agent bryostatin appears ineffective in the treatment of metastatic melanoma in patients previously treated with chemotherapy. It should, however, be investigated further in previously untreated patients.

Inspired by the high response rates achieved with the DBCT regimen (dacarbazine [DTIC], carmustine [BCNU], cisplatin and tamoxifen [TAM]), we administered the nitrosourea compound fotemustine, cisplatin and TAM (FCT regimen) to 69 patients with metastatic melanoma. Fotemustine (100 mg/m2) and cisplatin (100 mg/m2) were administered every 4 weeks, preceded by TAM 160 mg daily for 7 days from the second course onwards. Pharmacokinetic blood sampling was performed in 14 patients during the initial two cycles to compare the pharmacokinetic behaviour of fotemustine with or without TAM. Previous chemo- or radiotherapy was allowed, and patients with brain metastases or concomitant other malignancies were included. Four complete and 11 partial responders were observed among 66 evaluable patients, yielding a response rate of 22.7% (95% confidence interval 12.9 32.5%). The median survival time was 6.4 months (range 0.1-52+ months). The main toxicities were thrombocytopenia, protracted nausea/vomiting and ototoxicity. Renal toxicity was generally mild, but possibly contributed to two deaths. Seven patients experienced deep venous thrombosis during the study. TAM had no influence on the pharmacokinetics of fotemustine. The activity of the FCT regimen was clearly inferior to that initially reported with DBCT treatment. However, a recent publication concludes that the latter achieves a considerably lower response rate when administered to a larger patient group. We believe our results reflect the true activity of FCT and similar regimens when administered routinely to unselected patients. Considering the number of potentially serious side effects, we cannot recommend the moderately active FCT regimen as a palliative treatment option for melanoma patients.

Melanoma is an uncommon disease in Japan. The incidence, however, has been gradually increasing in the last two decades, as in many other countries worldwide. Ten patients with metastatic malignant melanoma were treated between March of 1997 and April of 1998 in the Department of Dermatology, National Cancer Center Hospital, with a combination chemotherapy consisting of dacarbazine (DTIC), nimustine hydrochloride (ACNU), cisplatin (CDDP), and tamoxifen (TAM). The patients characteristics were as follows: four were males and six females; the age range was 33-70 years; all were Japanese; sites of primary disease: extremities 4, primary unknown 3, nasal cavity 1, anus 1, scalp 1; sites of metastases: lymph nodes 6, pulmonary system 5, skin 2, liver 3, gall bladder 1, adrenal gland 1. The chemotherapy regimen included DTIC 220 mg/m2/i.v. on days 1 through 3, ACNU 60 mg/m2/i.v. on day 1, cisplatin 25 mg/m2/i.v. on days 1 through 3, and tamoxifen 10 mg p.o. twice daily. One patient achieved a complete response and 3 showed partial responses. The response rate was 40%. The four responders included those with metastases to the nodes, lung, and liver. The main toxicities were nausea, vomiting, leucopenia, anemia, and thrombocytopenia. This regimen is a fairly effective combination against metastatic melanoma.

A phase II study was undertaken to determine the efficacy of tirapazamine combined with cisplatin in patients with metastatic melanoma between April 1996 and April 1997. Tirapazamine 390 mg/m2, administered i.v. over 2 h, followed in 1 h by cisplatin 75 mg/m2 over 1 h, were used every 21 days to treat chemotherapy-naive patients with metastatic melanoma. Objective tumor measurements were used to assess efficacy of the regimen. NCI common toxicity criteria were used to grade toxicities. Forty-eight patients with metastatic melanoma of cutaneous or mucosal origin, none with symptomatic brain metastasis, were treated. Nine patients had a partial response, with an overall response rate of 20% (95% confidence interval: 9-33%). The median duration of response was 6 months. Grade 3 nausea, vomiting, anorexia, muscle cramps and fatigue occurred in fewer than 10% of patients. Neutropenia and thrombocytopenia were rare. This outpatient single-day administered tirapazamine-cisplatin regimen has definite activity in chemotherapy-naive patients with metastatic melanoma. Further studies in combination with other agents active against this disease are warranted.
